Annotate PDF for authors
Updated July 2026
Arthize lets authors and self-publishers annotate a PDF in a private workspace — free, with no watermark. Annotating a PDF adds highlights, comments, shapes and notes on top of the page, so you can mark up a document without changing its text.
Why authors annotate a PDF
An author merges manuscript chapters into one file, resizes the pages to the print trim size, and exports a clean, watermark-free PDF for the printer.
Built for manuscripts. Whether it's manuscripts, proofs, cover files, Arthize's annotate pdf keeps the work inside your private workspace. Unpublished manuscripts are valuable IP; private processing keeps them off public servers.
What matters when you annotate a PDF
Annotations sit on top of the page and don't change the underlying text.
You can highlight, comment, draw and add notes.
Annotated files are ideal for review and feedback.
